Original Press Release:

Full Range Ultra High Resolution Spectroradiometer

The SR-6500 is designed for applications that require superior spectral resolution.

The SPECTRAL EVOLUTION SR-6500 NIR spectroradiometer covers the UV/VIS/NIR range from 350-2500 nanometers. It features ultra high resolution and very stable performance with three high density thermoelectrically cooled photodiode arrays. The SR-6500 is also calibrated to NIST-traceable radiometric calibration standards.

Resolution at FWHM for the SR6500 is:

• 1.5nm @ 700nm

• 3.0nm @ 1500nm

• 3.8nm @ 2100nm

Resolution is achieved using three high density solid state thermoelectrically cooled photodiode arrays:

• 1024 element TE-cooled silicon phtotodiode array detector (VIS-NIR)

• 512 element TE-cooled InGaAs photodiode array detector (SWIR 1)

• 512 element TE-cooled extended InGaAs photodiode array detector (SWIR 2)

The SR-6500 features the following Noise Equivalence Radiance (NER) performance with a 1.5 meter fiber optic:

• 1.0 x 10-9 W/cm2/nm/sr @ 400nm

• 2.8 x 10-9 W/cm2/nm/sr @ 1500nm

• 6.8 x 10-9 W/cm2/nm/sr @ 2100nm

NER is a measure of instrument sensitivity. Other features of the SR-6500 include:

• All fixed optics – no moving parts for rugged reliability

• Auto-exposure, auto dark current shutter

• DARWin SP Data Acquisition software saves all scans as ASCII files for use with other software programs

The SR-6500 includes wireless Bluetooth and USB communications and has an operating range from 0-40°C. Physical parameters include:

• Dimensions: 12.4 x 8.7 x 4.4 inches (31.5 x 22.9 x 38.7 cm)

• Weight: 11 pounds (4.99 kg) What kind of applications will benefit from the higher resolution?

• Mineral identification and analysis where resolution can help to distinguish between minerals with very similar spectra or to unmix and identify minerals in trace amounts.

• Soil studies for the identification of different soil characteristics, clay types, presence or absence of nutrients and moisture.

• Vegetation studies for plant stress/health, over-fertilization, species identification and more.

• Lab applications such as materials identification, etc.

• Solar radiance and irradiance research.

• Microbial diversity research
